Please provide your WebSocket client code, or switch to using the one provided by Swoole. My test was correct. Server<?php
$server = new Swoole\Websocket\Server('127.0.0.1', 9502);
$server->set([
'open_websocket_ping_frame' => true,
'open_websocket_pong_frame' => true,
]);
$server->on('start', function ($server) {
echo "Websocket Server is started at ws://127.0.0.1:9502\n";
});
$server->on('open', function ($server, $req) {
echo "connection open: {$req->fd}\n";
});
$server->on('message', function ($server, $frame) {
echo "received message: {$frame->data}\n";
if ($frame->opcode === WEBSOCKET_OPCODE_PING) { // WEBSOCKET_OPCODE_PING is 0x09
echo "Ping frame received: Code {$frame->opcode}\n"; // Ref.: See Output-1 after code snippet
// Reply with Pong frame
$pongFrame = new Swoole\WebSocket\Frame;
$pongFrame->opcode = WEBSOCKET_OPCODE_PONG;
$pongFrame->finish = true;
$pongFrame->data = 'hello';
var_export($pongFrame); // Ref.: See Output-2
$server->push($frame->fd, $pongFrame);
} else {
$server->push($frame->fd, json_encode(['hello', 'world']));
}
});
$server->on('close', function ($server, $fd) {
echo "connection close: {$fd}\n";
});
$server->start();Client<?php
use Swoole\Coroutine\Http\Client;
Co\run(function () {
$cli = new Client('127.0.0.1', 9502);
$cli->upgrade('/');
$cli->push('hello', WEBSOCKET_OPCODE_PING);
$frame = $cli->recv();
var_dump($frame->opcode == WEBSOCKET_OPCODE_PONG);
var_dump($frame);
});OutputServerphp ws.php
